Many causes of autism, including environmental and genetic factors, have been recognized or proposed, but understanding of the theory of causation of autism is incomplete. [1] Attempts have been made to incorporate the known genetic and environmental causes into a comprehensive causative framework. [ 2 ]
The theory of mind hypothesis is supported by the atypical responses of children with autism to the Sally–Anne test for reasoning about others' motivations, [67] and the mirror neuron system theory of autism described in Pathophysiology maps well to the hypothesis. [43]
Autism spectrum disorder [a] (ASD), or simply autism, is a neurodevelopmental disorder "characterized by persistent deficits in social communication and social interaction across multiple contexts" and "restricted, repetitive patterns of behavior, interests, or activities". [11] Sensory abnormalities are also included in the diagnostic manuals ...
Autism has multiple causes. This article focuses on heritable causes. The heritability of autism is the proportion of differences in expression of autism that can be explained by genetic variation; if the heritability of a condition is high, then the condition is considered to be primarily genetic. Autism has a strong genetic basis.
The refrigerator mother theory, also known as Bettelheim's theory of autism, is a largely abandoned psychological theory that the cause of autism is a lack of parental, and in particular, maternal emotional warmth.
One of the leading theories of a potential pathogenic process in ASD is cortical hyperexcitability. Maintaining proper levels of cortical excitability is essential for many important cognitive functions, such as processing sensory information, [18] communication between different regions of the brain, and neural plasticity. [19]
Indeed, when asked by Sen. Bill Cassidy (R-La.) whether he would unequivocally say that certain vaccines do not cause autism, Kennedy danced around it, simply saying, “If the data is there, I ...
Classic autism, also known as childhood autism, autistic disorder, or Kanner's syndrome, is a formerly diagnosed neurodevelopmental disorder first described by Leo Kanner in 1943. It is characterized by atypical and impaired development in social interaction and communication as well as restricted, repetitive behaviors, activities, and interests.
